From #1 bestseller and USA Today bestseller Morgan Rice, whose books have over 10,000 five-star ratings, comes the fourth book in an astounding new fantasy series, VOWSWORN, ideal for fans of Sarah J. Maas, Callie Hart, and Holly Black.

In the Five Kingdoms of Valterra, magic comes with a price—sacred oaths that grant incredible power but must never be broken.

As turmoil grips Northaven and Lady Maren positions herself for power, Briar finds herself in the most dangerous place possible—the dungeons of her former home. Kieran races back to the kingdom carrying forbidden knowledge, desperate to save the woman he loves.

Meanwhile, Lysandra breaches the castle with her own agenda, driven by an oath that consumes more of her humanity with each passing day. As foreign invaders push inland and the kingdom fractures from within, three paths converge in a confrontation that will change everything.

In a land torn between invasion and civil conflict, can Briar reclaim not just her freedom but her vision for a better future?

And as ancient powers shift and transform, who will rise from the chaos to shape Valterra's destiny?

A breathtaking world where magic and passion collide, VOWSWORN offers immersive worldbuilding and characters caught between heart-wrenching choices. Once you enter the world of the Vowsworn, breaking free may be impossible.

Future books in the series are available!
